CASE FOR PHOTOGRAPHIC SENSI TIZED PAPER.

SPECIFICATION forming part of Letters Patent No. 337,963, dated March16, 1886.

Application filed August 19, 1885.

To all whom, it may concern:

Be it known that we, WILLIAM H. LEWIS and ERASTUS B. BARKER, both of thecity, county, and State of New York, have invented a new and ImprovedCase for Photographic Sensitized Paper or Tissue, of which the followingis a full, clear, and exact description.

Our invention consists of a light-tight box havingalight tightpassage-way for the movement of the paper sheet into or out of the box,and which is light-tight both when the sensitized sheet is wholly withinthe box and when it is being moved in or out of the same; and theinvention comprises various constructions and combinations of parts,including a roller within the box as above for carrying the sensitizedsheet, and which is made capable of being operated from the exterior ofthe box for drawing in, out, and storing the paper or sheet.

The invention also includes various other constructionsand combinationsof parts, whereby the efficiency of the case is very perfectly secured,substantially as hereinafter shown and described.

The invention is applicable to carrying, preserving, and supplying asrequired all kinds of flexible sensitized tissue or paper, whethersensitized on one or both sides, and whether used for making negativesor for photographic printing.

Reference is had to the accompanying drawings, which form part of thisspecification, like letters of reference indicating like partsthroughout the several figures of the drawings, and which illustratesone form or construction of the case embodying our invention.

Figure 1 represents a view in perspective of the case closed asconstructed in the form we prefer, said View also showing a portion ofthe flexible sensitized tissue or paper carried by the ease as in theact of being drawn therefrom, likewise showing a key used in connectionwith the case detached. Fig. 2 is a perspective view of the case whenopen; Fig. 3, a longitudinal vertical section of the case closed; Fig.4, a back view of the same; and Fig. 5 a vertical transverse sectionupon the line at a: in Fig. 3. Fig. 6 is a transverse sectional viewupon a larger scale of the roller which carries the paper, showing morees- Serial No. 174,802. (No model.)

pecially a special construction of it for attachment of the paper to it.

The case, as shown in the drawings, is mainly made up of an oblong boxor body part, A, and corresponding-shaped lid part A, hinged to the boxpart in the rear, as at a a, and passing at its ends when being closeddown within plates 1) b, secured to the ends of the box part. The box orcase, whether thus or otherwise constructed, is to be provided with alongitudinal passage-way for the movement of the paper to and from theinterior ;of the box, and this passage-way is made light-tight in anysuitable manner. One method of making said passageway lighttight, andthe one which we prefer, is shown in the drawings, and may be describedas follows: L is a longitudinal opening or slot in the box, the upperedge of which is fitted with a packing strip or wiper, I, of softflexible material, such as cloth, and which forms the upper lip of saidpassage-way. Said wiper, as for instance, when the longitudinal openiiigL is formed, as shown, in part by the lid and in part by the body or boxpart of the case, may be secured in any suitable manner to the interiorof the lid. Immediately below andin contact with said wiper I is asnlalllongitudinal roller, H, which is journaled at its ends in the endplates, b 'b, of the box. Said roller H constitutes the lower lip of thepassage-way, and this roller, together with the wiper l, are so adjustedin respect to each other that there is a passage-way, 0, between themfor the paper, which passage-way is light-tight both when the paper isintroduced between the roller H and wiper I and also when the paper iswholly withdrawn from between said parts.

To prevent the access of light to the interior of the box at the lowersurface of the roller H, We arrange another longitudinal wiper, J, ofsuitable soft material, to bear against the under side of the roller H,as shown. This second wiper, J, may be attached to the interior of thebox part of the case by any suitable means.

Arranged longitudinally within the box or body part A is a roller, B,which carries on IOO sheet being entered down within alongitudinalrecess, d, in the roller and engaging with pins or pointed teeth 8therein, which project obliquely in a downward direction from one wallof the recess d toward the other wall, whereby a firm hold is obtainedfor the paper without exposing it to being punctured otherwise than atits end through a single thickness, thus preventing the marring of thesheet or roll of sensitive paper.

The roller B, which may be wood or other suitable material, is protectedat its ends by ferrules D, which are constructed with outer tubularcentral necks or externally circular sockets, 6, whereby saidferrulesare alsomade to form journals for the roller, and by suitably shapingthe interior of said sockets provision is made for introducing a key, E,to engage with the roller for the purpose of rotating it to roll or takeup the paper, either when first charging the case or in the event ofmore paper being drawn out than is necessary at any one time. Byarranging these ferrule-journals at both ends of the roller carrying thepaper, opportunity is afforded for turning said roller by its key fromeither end of the case. Said ferrule-journals have their bearings in theplates b b, which thus form journal-boxes, as well as end covers to thecase, constructed to exclude-light from entering at the end joints ofthe case. i

To prevent the too free turning of the roller B, or, in other words, tothrow a resistance upon it by friction, which will retard its run and sofacilitate the drawing out of the sensitive paper from the case inmeasured or desired quantities, cupped spring-washers G are introducedat the ends of said roller, between it and the ends of the case, therebyproducing an endwise pressure against the roller. The roller H alsoserves as a guide for the tissue or paper as it is drawn over saidroller from the interior of the case by draft on its outer end from theside of the case having the opening L, to supply or measure off anydesired amount of paper, which isthen torn oft immediately in front ofor close up to the guideroller H, thus leaving the remainder of thepaper under the close and light-tight cover of the case. Furthermore,the two wipers I J are arranged so that the one wiper acts on thefriction or guide roller H throughout its length to keep it clean orfree from dust, and the other wiper acts on the tissue or paper itselffor a similar purpose, thereby preventing injury to the sensitizedsurface of the paper by dust collecting on it. This is in addition tothe hereinbefore described other and main function of saidwipers-namely, of excluding light from the interior of the case,andwhich, if admitted, would destroy the usefulness of the tissue or paperfor photographic purposes.

To more effectually exclude the light from the interior of the case whenclosed, the lid has not only a close fit'at its ends under cover of theplates b b, but a tongue-and-groove fit,

as at g, with the box part of the case along or in line with the hinges,and the case is held close shut and friction thrown upon the wipers I J,roller H, and tissue 0, passing over said roller, by spring-buttons K,applied to the back of the lid A and box part A. By suitably turningsaid, buttons, however, as shown by dotted lines in Fig. 4, the case mayreadily be opened when required to introduce a fresh sheet or roll oftissue, or as other circumstances may render necessary.

The case, as thus described, for storing photographic sensitive papermay be carried in the pocket or elsewhere without risk of exposing saidpaper to light or dust, and the paper may be torn off for use in lengthsof any desired size without affecting or exposing the remainder, and thecase will be found much more convenient in this and other respects thana portfolio carrying between its leaves detached lengths or pieces ofphotographic sensitive paper.

Having thus described our invention, what we claim as new, anddesire tosecure by Letters Patent, is

1. As an improved article of manufacture, a light-tight case for thestorage and delivery of continuous rolls of photographic sensitive paperor tissue, made substantially as described, the same consisting of acase adapted to contain a continuous roll of the sensitive material, andprovided with a longitudinal slot having one or more flexible lipsthrough which portions of the roll of sensitive tissue may be withdrawnas desired, while access of light to the tissue remaining within thecase is prevented, all as set forth. 1

2. In a case for storing photographic sensitive paper, the combination,with a lighttight box having a light-tight passage-wayfor the movementof the paper sheet into or out of the box, of a roller operated from theexterior of the box for drawing in and out the paper, as set forth.
